Need help with FD feed wheel offset fitment and tires



I have an FD with the front and rear fenders and need help with offset and tires. I’m planning to buy the Gram Lights 57DR with 18x9.5 front and 18x10.5 rear and need help with offset and tires sizes. I want to set it up close as possible to this one above. Thanks

In the "post pics of your fd" thread, you can find all the information you could need.

a 9.5+15 Will give you want for the front and a 10.5+15-20 Will give the rear fitment you want.

tires vary too wildy with how they fit to make any recommendation. I'm using bfg g force sport comp 2 and they're not "meaty" but they do fill out pretty nice. Keep in mind with super flush fitment like that there's good chance you can and will rub without some camber or raising the car up.

thanks. Been looking around and I found a bunch of offset so I wasn’t sure which would fit exactly like the one that’s pictured.

You do know the car above is a wide body correct?

Im sure he does.... the title of the thread and the first sentence of his post hints at it a little bit

9.5 +15 with 235/40-18 and
10.5 +15 with 255/35-18
... will those will fit under stock rolled (but not pulled) fenders and stock suspension arms?

While I'm at it, what do people do with the front inner-fender lining when lowering more than an inch or two and rolling fenders? Just toss it? (Will also refer to the posts referenced here! thanks!)

definitely will NOT fit under a stock front regardless of modification. The 9.5+15 is ultra flush on my feed front in a 17. I can't imagine what an 18 would look like without some aggressive camber. The 10.5+15 might fit in the rear with some super aggressive pulling and rolling but I doubt it. Those sizes are more for the wide"er" body cars or the camber boys. You can push the limits of the stock body but you're going to be destroying stuff for the sake of the look and that's dumb.

keep your fender liners. They're important. Over time, they do shrink and cause the wheel to rub them in places where it normally wouldn't. If that's the case, you can make relief cuts in them to compensate or buy new ones. Without the liners you leave your front harness exposed and your engine bay open to whatever your tires kick up...... which is everything.

Thanks for the input!!
Since that post, I have kept doing research... People seem to say 18*9.5 +22 will fit up front with a roll and a couple degrees of camber. I don't mind going up to -3 or -3.5 deg camber.
Does that sound right?

Fender liners also seem to be the only thing between the front inner wheelwell and the engine bay, so I can see their importance.

I'm Keen to hear and see what others have done with the fender liners to accommodate large tires or super low suspension.

How about the tabs on the fender that hold the inner fender liners in place - doesn't rolling your fenders make them useless? How does the liner stay in place without them?

Thanks and sorry if these have obvious answers - I haven't taken delivery of my car yet and am working on photos and guesses!

Wow. I just checked the feed website, and it specifically says that the fender is about +25mm over stock, and can take a 9.5j wheel with offsets of around 24 - 22, or (I deduce) lower if you process the fender and/or have out-of-spec (negative) camber..
There you have it.
